That just means it can't move on it's own, but can it be moved with the help of something/s with a powerful tractor beam/s or big enough to gobble it up?
Stations used to be able to be loaded into bays, that could hold them, via tractor beams.
As far as using a beam to move them insystem... I don't think so. I recall Lilith mentioning something about her T2 docking a LSC. Which then couldn't undock.
Or something.
Again. This used to be the case. I have no clue. I have nothing free, large enough to try and see at the moment.
