Given that we're talking about cell phones, it seems completely
likely.  Cell phones present the dialed number as a block, so there's
no ambiguity between 911 and 911XXXXX.  I don't know whether UK cell
carriers map 911 to 112, but there's no technical reason they can't do
so.

I agree that for VoIP using normal phones through adapters, 911 in the
UK won't work.
