No, Vertigo is an entirely different phenomenon.
But vertigo and motion sickness are commonly conflated terms. So much so that patients who have read too much Internet junk medicine will come in complaining of motion sickness when they actually have Vertigo and vice versa. Or they'll say they have Vertigo when they actually just have nausea. And so on and so forth. Vertigo is not Disorientation (although it can make you quite disoriented, when it occurs).
Still, I'd make the Motion Sickness negative quality affect you only if not in AR/VR. Possibly give a lowered benefit for people who are hackers/technomancers, as it would affect them less if it didn't affect you in AR/VR (it shouldn't, in VR, because of the various "cutoff" systems you have when you go full VR). We already have Simsense Vertigo, and if you wanted a character that was disoriented in simsense AND in moving vehicles, you can pick up both negative qualities, I guess.
