Absolutely. The best way to remove the rail from its clips is to use a screwdriver. Wrap a piece of cloth around the screwdriver head to prevent damage to the rail.
Place the screwdriver at the bottom of one end of the rail, between the rail and the wall and carefully move the screwdriver upwards, pulling the rail loose from its installation clips. Once you have made a start, you can gently loosen the rail by hand.
Typically you will find it is very easy to slide the rail on and off the screws despite the fact the system is very secure when in place and with works hung.
