You can do whatever you want, just be aware that festivals do ask about rights clearances and it can bite you in the ass. I know several people who have had issues not only with festivals but they had trouble selling their shorts in markets because of it.
If this is a short film that no one will see and that you'll screen for your friends late at night in the basement with milk and cookies, go for it. But if you want a wider audience it might be worth working around it.
if you have a trademark that can identified in your film you will not need to clear it if: you are not committing trade libel, and the trademark is used as it is intended to be used without any consequences of its uses being abnormal or out of the ordinary.
Applying the facts involved in your film to the above statement is the film makers responsibility when deciding to have something identifiable in the film, but that is the general rule.
