In general I would say yes, unless you plan on sitting exactly centered between the front speakers. The center channel helps a lot with centering the dialog onto the screen if you are sitting off to the side.
Now having said that it has been my experience that the center speaker always sounds a little different from the mains and going with only two front speakers results in a more seamless sound when the sound pans across the screen. That is with inexpensive equipment - high $ stuff may be better.
