Re-filling central heating system with 1 rad removed

Provided that the valves at both ends of the removed radiator are turned off and watertight.
Count the number of turns on the regulating valve, so you can open it to the same position when you replace the radiator.
If the control valve has a thermostatic head make sure it has a decorator's cap fitted to ensure it stays shut.
When refilling have bowls and towels ready in case either valve is not fully shut. Central heating valves do sometimes leak as they are often operated infrequently.

In an earlier contribution to this discussion,
I would also make sure that the pipes to the disconnected radiator are full of water, to reduce the risk of airlocks upstream which may affect other rads. You can do this, once you've filled most of the system, by cracking each valve open with a bowl under it until water rather than air comes out - then shutting it again.
