Why not? I let the motor spin the platter for two days (without playing the needle). Most bearings freeze if they are not used for a longer time. I have seen a lot of shops, that let their Rega's spin all the time to avoid warm up and restarts of the AC motor. Aren't Nottingham tables designed to run without stopping and starting?
Breaking in the needle is more difficult: I usually use some Records that I don't like, change them every 20 minutes and try not to listen. At least this get's me past the first 10-20 hours. In particular the Denon DL103 was a pain before it was actually listenable.
