If you are not particular about the fit of the cap to the truck cab lines, yes you might be able to use one for another brand of truck.
But, truck caps are usually made to a particular make and style of truck. I have a ARE brand cap (4are.com) MX style for my 2007 DC long bed. It has a higher than cab height. That model is not available for the CM. Look at their web site for what is available for the CM. Leer also makes caps for your truck. (leer.com) Good luck with your search.
