Oh no, it's actually an example of the ridiculousness of TV crossovers. Maybe 90% or more of the connections are subtle nods by writers or directors to other shows to be funny. I think a couple are just re-using the same props for invented products. Very rarely are they intentional.
Yoyodyne just as a funny, not real aerospace company name, gets used in Star Trek as a typically non-visible text on panels. I first heard of it from The Adventures of Buckaroo Bonsai. I'll sure the books by Pynchon were influential sci-fi read by people working on those, and no one ever thought it would be used for some 400+ show/movie crossover list.
Not really. If confirmed, it means someone somewhere was smart enough to do something like drive across a border in a truck with fake papers. It's very, very unlikely that Nvidia directly sold to anyone in a way that would get them in trouble.
