Those are all too clean for 1983 Microsoft. I'm more likely to think it's some cutting inside joke, maybe an IBM insult.
If they said it was say, something like George Wallace Basic, because they segregated it from IBM basic and only put it on the clones as a "separate but equal basic" I wouldn't think twice.
I can even imagine the meeting
"We can't say this is George Wallace basic, no".
"Fine, it's GW basic. Say it means gee wiz or some shit, just make something up"
