No but effectively yes.
By the time the B-15 got to B-15C, it was very close to an MA-1, except the collar.
The fur collar of the B-15 was deemed a fire risk, so jackets were recalled to have it removed and replaced with a knit collar (that’s the modification in question). Subsequent jackets were made with the knit collar from the start, under the MA-1 contract.
There are some differences like how the MA-1 marked a return to green (B-15 jackets had shifted to blue to show the Air Force’s new identity as a separate branch, however for obvious reasons, dark blue was not good camo!)
The return to the green was made by the B-15D after many pilots in the field in Korea preferred the older, B15-B over the C when they could get one, green being less obvious if downed in enemy-controlled territory... There were B-15D-Mod jackets as well, even more indistinguishable from MkI (pre-orange liner) MA1s.
As well as apparent fire risks, I've also heard it said that the knit collar design was much less likely to foul on various plane harnesses and such by that point. I'm not sure, though, how accurate that is, given there are a lot of legends spring up around this stuff.
I didn't originally care for the MA1, but I've grown to enjoy the design more in recent years, based on its practicality. Although an anachronism, a nomex MA1 would be quite something.
