The regulations require that you have sufficient fuel on takeoff. They do not require
that you have the required reserve when you land. If checked, you might be required
to demonstrate how you calculated the reserve. You might be violated if they think
you did not do a good job of that. I've never heard of such a case in non-commercial
flights, but it's certainly possible.
