The satellites are moving rapidly relative to your position on earth, so you are not tied to a single satellite.
But you are tied to a location (so the satellites know where to expect you). And yes, this location can be changed - the system just has to know about it. It is up to Starlink under what circumstances they allow this, and you can expect there to be issues in some locations with too many customers or with licence restrictions.
They are working on an antenna for moving vehicles, but size and cost (and possibly power use) are likely to limit this for private users, and the physics suggests that it is unlikely to happen for vehicles as small as a car.
