Yes, but why would you?
a friend of mine lived in Germany for 5 years (after 5 years in Zurich), he worked as a compensation consultant for (big) banks and being from US he never bothered himself with the German language, since all the banks are using English as their lingua franca.
BUT: he hanged out only with his bank colleagues (yeah, with me and a few other social folk also), but spending 10 years in an environment, where your contacts are limited to just the (professional) folk around you with your language, never been really able to have some more deep, sophisticated conversations or even following regional TV, cinema and all that: what´s the point in all that?
To me it´s just a great waste of opportunity, it´s not making use of all the cultural (and human) diversity around you, so: YES, it´s possible (at least in the cities), but I strongly advise to spend some time (and money) to learn the language of the people around you, even if it´s only for some few years!
