In the MCA files, you will get a "horse" tag, but you'll have to decide which class to use, then have at least 2 separate functions for loading horses - the normal ones and the undead ones - because they won't have a common horse ancestor. It's not impossible, just... impractical.
Do the undead horses even burn in vanilla? I've never seen one, as far as I know, they aren't obtainable without editors.
I've watched a few videos, the horses don't burn. No point in making them a separate class, then.
