If only it were that simple. It's not entirely accurate. Especially for the Commodore 64 crowd which pre dates the NES and Gameboy. That thing used PWM's all over the map, and other sound waves.
Also, what about all the chiptunes that don't use square waves at all for their composition? Many Sega Genesis and FM Arcade games that avoid simple square and pulse waves altogether. Yet they are entirely authentic chiptunes and have a unique "chiptune" aesthetic and feel without square waves.
My claim is that the "feel and aesthetic" of chiptunes is entirely subjective to each individual and what they grew up with. So your claim is incomplete, and does not apply to necessarily everyone, such as the demoscene crowd in the UK with their crazy C64 and Amiga music.
But technically, yes, if a person grew up with an NES and a Gameboy only, then the 50% square is commonly used on those game.
So I would agree that the majority of people in the US who were raised with only Gameboys might have the misconception that square waves are "defining" of chiptunes. The truth of the matter is that most gamers, at least, in the US have heard other chiptunes that don't make heavy use, or any use of square waves, like SNES, Genesis, Amiga, TB-16, etc.
(P.S. Yes, I know it's possible to produce 50% square waves on all those systems, but they were not used all the time like on NES and GB)
