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.
