Baseboard heater efficiency question

One of my hot water baseboards is behind a small couch (about a foot from the wall).
Would it radiate more (less) heat if I removed the front cover of the heater?

Hot water baseboard is designed to transfer heat primarily by convection, not radiation. The air around the finned coil is heated, expanding the air. The warmer lighter air then rises, drawing more, colder air in to be warmed. This creates a convective current.
As long as there is room under and behind the couch for air to flow freely, the baseboard will do its job quite well.
