No, "se" here is Latin in the same way that "exempli" and "gratia" are. You similarly can't use "kung" or "fu".

That said, you may not like this answer, but ultimately whatever's in the official dictionary (now known as Collins Scrabble Words / CSW) is what goes. "mein" as in "chow mein" is not valid (nor is "chowmein"), but "lomein" and "wonton" are.
