You can use a registered suppressor on anything you want. However, Cans are usually designed for very specific calibers, and/or guns. If the threads match up, you could use that .22 can on a .22-250 rifle....legally, but it would surely destroy the can and may even be dangerous.
There may be one exception to this - integrally suppressed guns. I don't think that you can take an integrally suppressed barrel and use it on another gun, but I'm not sure about this.
