I've actually predicted that vWii couldn't play out-of-region WiiWare and VC games before, but today I installed WarioWare D.I.Y. Showcase (NTSC) into my vWii. When I launched it, it gave me the "This channel can't be used" error screen, and this is proof that out-of-region WiiWare games can't be played on Wii U, although I had some VC injects on my SD Card Menu, and they launched and played just fine.
I'm thinking of using FreeTheWads or ShowMiiWads to region-free my WiiWare WAD, but I'm doubting it, and I need someone to test it for me in case.
