On a single battery mech mod it's not safe. With a dual parallel mech mod theoretically it's possible as the amp draw is devided between each battery so 14 amps will be drawn from each battery. But at this low resistance you would have very little wiggle room with 20a batteries. any sort of short or loose leg in a post could easy put you down as low as .1 ohm at which point you would be drawing 42 amps which is passed the safe limit for 2 20a CDR batterys run in parallel.
I wouldn't recommend anyone build that low on a mech even a dual parallel one myself. But if you're going to then you would be much safer running 2 30a CDR batteries like sony vtc4's in parallel which would give you a much better safety cushion.
1.0 ohm = 4.2 amp draw
0.9 ohm = 4.6 amp draw
0.8 ohm = 5.2 amp draw
0.7 ohms = 6 amp draw
0.6 ohms = 7 amp draw
0.5 ohms = 8.4 amp draw
0.4 ohms = 10.5 amp draw
0.3 ohms = 14.0 amp draw
0.2 ohms = 21.0 amp draw
0.15 ohms = 28 amp draw <---------------
0.1 ohms = 42.0 amp draw
0.0 ohms = dead short = battery goes into thermal runaway

I agree if you ask that question then the answer should be no, safety first! My advise is to learn battery safety, ohms law and don't go below .5 ohms ish. This is only my opinion but there is really no need to until you really understand what you are doing.
0.15 Ohms on a single 20a battery? Short answer, no. You'd need at the very least a 30a battery... but even then, you are pushing it. I would recommend a dual battery box mod for something like that.
No.
Your safety depends on your knowledge and attention to your hardware.
"parallel mod" ? That tells me you're not safe; you could have said a lot more about the mod.
"two 20 amp batteries"? That tells me you're not safe: you could have said exactly what batteries, and where you got them from, plus for vaping that low I'd expect to see vtc4.
"another regulated mod"?
could it be that you are using a regulated tc mod? dunno, again you didn't say; but if it's a tc mod that changes everything.
It isn't truly a 50/50 split between the batteries, differences in internal resistance of the batteries will set the draw from each. Also because you have two batteries next to each other mutual heating will de-rate them a bit further.
The OP states in the first line of his post that he is using two 20A batteries.
I agree with him. Run two vtc4 batts. I would personally run it in a regulated mod but that's up to you.

I see that. He must have edited it soon after posting or my lack of sleep has caused me to misread it... Though, I swear it didn't say two 20a batteries before...
That said... I think the OP needs to read up on electricity before proceeding any further.... and I have no clue what a "Tuglyfe mod" is.
An unregulated dual battery mod. Wired in parallel if I remember right.
The only time there is any value to building below .5 is when there is money on the line at a cloud competition.
And, even then, the cloud is mostly related to the capacity of an individuals lungs. Coil resistance is a distant 2nd.
So if you want to blow huge clouds, you will be better served by learning how to develop stronger lungs.
