From a technical point, yes, not lore-wise. Nomadic gypsy fox people are nothing like goblins.

Well, I have no idea what the future holds for Vulpera, and how much Blizzard even cares to implement lore-wise for them beyond perhaps "just a new allied race." You make a good point, but the same could be made for Pandaren, perhaps to a lesser extent since they did have an entire expansion dedicated to them, but not much since.
Just because Vulpera may not be your cup of tea, doesn't mean every allied race can't try to be original. Vulpera are polarizing, you either hate them or love them, but Warcraft can't be limited to just implementing pre-established lore. I appreciate Vulpera for what they are; in terms of allied races, you have to think outside the box. Sure, they likely won't be as well received over the long haul like Kul'tirans and Zandalar, or even Dark Irons as you pointed out, but they seem like they will be well-received better than mechagnomes. So while I might prefer Zandalar over Vulpera, I'd sure as hell prefer Vulpera over something like Lightforged Draenei or Mechagnomes.
They'll never know if it works if they don't try, and ugh... I would not have wanted "Gilgoblins" either...
We'll see how they immerse Vulpera into the Horde's story going forward if at all, but right now, at least they have their own backstory, however limited it might be and seemingly out of nowhere (Void Elves say hi. lol)
