The edit you made was undone due to conflicting with official sources. Its concept art clearly refers to it as a Dragon, and until RT releases a statement about renaming it, we’ll call it a dragon on our pages.

In addition, if you take a look at the trivia section, you may notice RT already addressed te similarities between the grimm’s design and wyverns. Nevertheless, they still call it a dragon.
