Yeah, Kroloteans are canon. The also appeared early in Green Lantern Vol 4.

Some others are definitely canon, such as the Trogkian Mammoth and Selachian. Green Lantern/Sinestro Corps Secret Files and Origins Vol 1 1 gives races in some cases, but only home planets in most. The same goes for Legion: home planets are mentioned just about every issue, but race names aren't, if at all.
