Yes, because it is already registered in RFC 3805:

        langPCLXL(47),       -- Not in RFC 1759
                             -- Printer Control Language. Extended
                             -- language features for printing, and
                             -- printer control.
                             -- Tammy Ferguson (HP)
                             -- and Binnur Al-Kazily (HP)
                             -- Technical reference manual: None
                             -- Hewlett-Packard Co.
