Satellites can be moved, for example to avoid a collision with another satellite or debris, or to semi-permanently change the orbit. They have some sort of propulsion to allow this, and also counter atmospheric drag etc.
However, the lifetime of the satellite is generally limited by the amount of propellant (or whatever), after it's run out the satellite is useless. So it's not done on a whim.
