Uber Black perhaps, but not UberX, which is by far the focus of Uber now. Around here Uber specifically advertises UberX as a taxi, and openly does price comparisons between it and taxi fares (as opposed to price comparisons against other limo services).

Let's also not forget that Uber started as Ubercab and was forced to change their name. I don't think they ever intended to be a limo service, and their current product offerings are largely not limo services.
