Yes - there is no age upper limit written in the law. However it does include this exception at 29 U.S. Code § 623(f)(1): allowing an employer -
(1) to take any action otherwise prohibited under subsections (a), (b), (c), or (e) of this section where age is a bona fide occupational qualification reasonably necessary to the normal operation of the particular business,
and there may be actual job requirements that a specific older person might not be able to perform and therefore they would be eliminated from further consideration legally.
