Sure. You should be able to add them to any available GPIO. On the Freeplay CM3, if you remove the Pi Compute Module, you may notice some small circles labeled 35, 36, 37, 38, and 39. These can be used for multiple things, but they should be find for buttons. You would want to solder one leg of a button to the pad and the other leg to GND.
After soldering them, you'd need to change the /etc/modprobe.d/mk_arcade_joystick.conf to add the buttons. Just pick one that's currently set to -1 and change it to whatever you soldered to (like change ,-1, to ,35,).
I hope that makes sense. Let me know if you need more info.
