I'd consider the Wyvern to be a miniboss:
 * 1) It's the only enemy which does not have a spawn message / music that -- as a single enemy (not counting groups) -- is comparable to the King Slime in terms of size, damage, and health.
 * 2) The King Slime is a boss.

That being said, it doesn't have a spawn message / music. So if the spawn message / music is an important criteria to you, then I guess you wouldn't consider it a boss.
