unless you buy the world's crappiest slicks made with the crappiest rubber and keep them under-inflated, the answer is almost unilaterally "yes" if your commute is 100% paved surfaces.
my bias is for the thinnest, highest-PSI tire you can reasonably put on the bike. i commute 30 miles everyday on my road bike with 23s @ 135 PSI and i love it! yes, it's a harsh ride, i can feel every single grain of sand i roll over, but i feel like i'm riding on a steel rail, and that's a marvelous feeling.
