can radiator be repositioned?

I have those old heavy steam radiators in my brownstone apt, and want to put covers on them. But one juts out of its little window alcove at an angle, sticking out about 2 inches too far, leaving a lot of space behind it. Could this radiator be nudged back a little bit? I know this would mean a slight adjustment to the angles at which the pipes elbow to connect with the radiator. Has anyone ever moved/reconnected these things?
