That's one way to know for sure.

Look at where the freewheel is threaded onto the hub, is there any gap between the threads on the hub shell and the actual freewheel? If yes than you can probably replace the freewheel with a cog and lock ring. If the threads engage with the freewheel completely then you can install a cog but no lock ring
I'm guessing it won't be possible since just about every wheel sold with a fixed/free hub only allows a cog and lock ring to be installed on one side.
