From my understanding, you can use a 5.56 suppressor on a 22. However it's generally not recommended because .22 is extremely dirty and will clog up 5.56 suppressor a lot faster.
I don't own a suppressor (yet) but I was looking at that question the other day...I'm planning on just getting a .22 suppressor.
