No, they can't, use-restricted licenses are non-free, by the FSF definition.

This is true, but the Free license cannot be use-restricted, or it ceases to be a Free license (if the copyright owner, owing no obligation to any upstream licensor, does it, they could add the use restriction to a Free license, but it would by that act cease to be a free license; that violates Freedom 0.)
