Only if you want to do it the inefficient way. The smart way is to use a few ion engines, letting them slowly enlarge the orbit until a lunar capture is effected, then tightening that orbit. No big strain on the station and far less fuel needed. Okay it takes a while, but that doesn't matter in this case.
