Anybody can propose anyone else for an award for whatever they like - whether it is accepted or not is another matter.
Many years ago some of the regulars of the Folk Club at the Nook in Holmfirth put forward Angela Roberts who was licensee at the time. She didn't get an MBE or an OBE but she was invited to the palace along with David, her husband. Anyone who remembers David can imagine the scene.
Angela was absolutely delighted, they had a wonderful time and David was on his best behaviour.
