No, Nidhoggr was a worm, he's explictly called that, and presented as such.

A wyrm is not a worm. While there were european dragons classified as worms, they were not the same thing we call worms, and Nidhoggr does not fall into that class of worm, especially since "Worm" dragons are from English Folklore, more specifically Modern English, not Norse Mythology.

Wyrm was an old english term for dragons or dragon-like creatures, and that's what maintains their difference between Wyrms and Worms. Modern Wyrms are represented, I admit, in a way similar to a worm, but Wyrms are not Worms when it comes to Dragon Classification.

Of course, there's the possibility of you taking the idea from Dungeons and Dragons, in which case I have to say that is a very retarded choice, for anyone with any actual knowledge of the subject can easily realize that DnD's representation of mythological and fantastical creatures is waaaaaaaaaaaay wrong.
