Some missions, yes. Others, no. It depends on the of things tracked for Gold. Things like accuracy or number of shots will need a full mission restart. When you finish a mission, it will let you know if you failed an objective because of restarting a checkpoint. It'll put an X in the box and say "Checkpoint" next to it.
