Yes, certainly.
But remember when layering with carnaubas over sealants that if you ever want to add more sealant then you need to thoroughly remove the topcoat of carnauba to allow the best adhesion of the new sealant layer to the old sealant base.
I used to play a lot with keeping a durable, long lasting sealant as a basecoat and topping with different types of carnaubas for effect.
