Absolutely not! Ask your trainer if he/she will let you borrow a lesson horse to ride and show. It is a great way to develop a bond with that horse and that will show in your riding. If you are an experienced rider (4 ft. jumping) than you can talk to your trainer about showing a horse that he/she has been working on, if they don't want to show the horse. These are some great ways to get more ringtime and show off your great skills as a catch-rider to a prospective sponser.
