Can you use a queen mattress on a queen headboard?

UH, NO! Absolutely not!!! You could cause a rift in the time-space continuom. You have to use a king headboard with a twin-size matress. Otherwise, you could violate your local tenants law. Doing so also has a very negative effect on your credit score. What a question! Maybe you could explain what you mean, because, if you mean what I think you mean . . . no, surely you can't be serious. The real answer is YES, you can use a queen headboard with a queen matress, of course.
