If the plane is called the Shadowfell, and it has an Underdark, what do you call it to differentiate it from the NORMAL Underdark? So when you say it, you know you're talking about the Shadowfell's Underdark?
Why does the shadowfell need an underdark?
Wasn't 4e trying to do away with pointless symmetry in the planes?
And even if it was necessary for some reason, why not consult a thesaurus or a dictionary or the wikipedia page that has a list of underworlds sorted by mythos and do some vowel/constant swaps?
I think it's also worth pointing out that "Shadowfell" is a fairly strong portmanteux, IMO. "Feywild" a little less so, but only a little.
PS:
The Shadowfell IMC tends to be the very deep underdark, toward the deep center of the earth, deeper than the deepest drow city, a land of the dead and dying not unlike Sheol or Hel or Hades or Xibalba.
And my Feywild tends to actually be places where arcane magic flows into the world, along ley lines, in deep wilderness where sentient beings rarely tread.
But I'm in favor of the planes all being part of The World, usually, in my campaigns.
