Physics wise I do not see it malfunctioning in any way, should vape pretty near as well as a round or hex shaped coil, the downside I would see would be airflow around it, with a round or hex shaped coil the air can wrap around the coil, with a square the air has to move along a larger flat surface before wrapping along two other sides compared to a hex shape for instance.
/edit
That or you would have to mount the coil where a corner faced the air flow inlet to split the air.

You can try it. Common sense whispers me square coil could be as good as round one, or it could be worse, but it could not be better.
I don't think it will work as well, areas the wicking isn't evenly against the coil sets it up for hot spots.
I vote insufficient data. I don't think there's any danger if it blowing up at all, but there's a complex interaction going on between the air molecules and the coil surface. The squareish corners might set up turbulence that will reduce vapor production. Or it might work the other way because a square has more surface area than a circle given identical internal volume. One thing: coil calculators will not be accurate. You'll have to build and measure. But have a smack at it and let us know how it works.
if you are going to try it rotate it 45°, that way the air hits two sides and then vortexes on the other two.
just an educated guess...

I dont see a reason why it wouldnt work, and as stated above a coil calc wouldnt work the same but the wraps might be close so it would have to take a bit of tinkering to get the ohms you want, also wicking would take a bit of fiddling to make sure the whole coil gets cotton, and keep the corner of the coil direct to the airflow so it covers as much surface area as possible. give it a go and let us know how it works out for ya, Happy Vaping 
You don't see many sharp angles in nature. Circles (2D) and spheres (3D) are much more common.
I understand your curiosity but I don't think it would work very well.

don't see any problem with doing that I made a few rectangular coils form my protank 3 BCCs in an effort to avoid using flavor wicks or dual coils and it worked OK. you would have to calculate the amount of wire use and the resistance.I don't think the online calculators work for anything but round coils
It might look pretty in a macro shot but I don't think it would be an enjoyable vape
why not?? they wrap wire around square cores in transformers....
now if they made square silica or cotton or rayon.... everything would be all squared away

I remember a time we said oooooo dont let the coils touch or it wont work right - the trick will be figuring out the wicking
If you made the opening the same size or a bit smaller than the thickness of a cotton pad....why not?? they wrap wire around square cores in transformers....
now if they made square silica or cotton or rayon.... everything would be all squared away
I'd think even of you had wicking touching the entire inside surface the corners would still get hotter than the rest of the coilwhy not?? they wrap wire around square cores in transformers....
Since cotton molds to the shape of whatever I don't think it matters if you made a square or triangle or whatever. I try to make longer coils for more surface area, and the extra material making a square could make it one less wrap, thats the only thing I can see that would be different.
Well someone tried it at least
