Theuns, I don't know the answer to what you asked, but there are some decals sets for NMF MiG 15's in Korea. Heres 3 I found.

I am guessing you don't want to buy extra decals. But the fact that there seem to be more NMF ones than Camo, and the camo doesn't seem normal practice for Soviet aircraft of the time, would suggest that the answer to your question is yes. The problem would be the markings, woul;d they have been the same in NMF as when the camo was applied.
