It would be bad marketing to advertise it as otherwise, og switch was called a switch because it's catchy and because ofc it switches and the lite is called a switch because it's a essentially a brand/product line. It plays switch games and does everything else, therefore it is the same product. You don't want to confuse consumers, especially when Nintendo also appeals to casual gamers and parents. I can imagine a parent being confused if it was called something else (lets just say they called it play-tablet) and asking 'what games does it play?' 'is it compatible with normal switch games?' etc
