In the manual it says......It's possible to detach the tripod collar by removing the tripod collar lock screw. For details
on this procedure, contact your nearest Nikon service center or representative office.
I think there is a screw in the the base of the Tripod Locking screw that you can unscrew that allow the complete removal of the tripod locking screw.
If you can remove the tripod locking screw then the tripod collar should be able to be removed or else you might be able to put a 'little' oil into the hole which may then free the lens. I think like Robert says you may have dirt or a little corrosion in the gap between the lens tripod collar and the lans body.
Good luck.
