That barrier serves more as sound deadening than anything else. I can't imagine how it's related to the airbags...but I'm not an automotive engineer either.
The barrier adhesive is a MF'er and I've seen the barrier destroyed as a result of removal. As a suboptimal compromise cut the barrier out, cut a line just inside of the ashesive, and then tape it back into place when done.
