No. Those are reserved for _any_ use. For example, 6.2.5 states:
31) An implementation may define new keywords that provide
alternative ways to designate a basic (or any other)
type; this does not violate the requirement that all
basic types be different. Implementation-defined
keywords shall have the form of an identifier reserved
for any use as described in 7.1.3.
