Well, the engines on the L-382 are below the chordline of the wing and the turbine section is "under" the wing in all senses of the word. I've reverse taxied on a number of occasions.
Seriously though, even if you disregarded legality and engine health, would it be possible to reverse taxi on an E-175? I would assume that reversers, if even installed would be cascade reverses, and I have heard it said that they wouldn't generate enough actual reverse thrust to move the airplane backward.
