Using PP Predicatively

Can you use the PP predicatively? For example, suppose I want to say “He is the undisputed victor.” Could I translate this thus: “Hic est victor indisputatus.” If so-- if at all besides context-- to be distinguished from “He was the undisputed victor”?

It would appear from sections 495 - 497 in Allen and Greenough that you can.

Thanks. I had seen it used like that several times, but was suspicious because some of the material was from readers.
