All i can say is that a keris is a keris whether it is a lurus (straight) blade or a wavy (luk) blade. If the only thing that hold one back from referring to a straight pesh-kabz as such is the straightens of the blade i don't really find that to be much of a problem.
David, the keris you show have straight blades not curved, now if a keris had a curved blade instead of straight (is there such a thing?) would it not have a specific name, probably so.
