it's possible to keep a laptop on, uh. on the charger, and remove the battery completely -- it pretty much turns it into a standard computer that can be moved, provided you switch it off first.

though, if you're like me and using a specific brand of universal charger that sometimes has the damn charger come out of the, uh. the connector to the port, then you're a bit screwed unless you figure out a way to have that not happen.
