You might be able to. It also depends on the servo load. If you are running one lower power/speed servo, you should be ok.

However, I always recommend a UBEC over 3s or 8 cells. The ESC will just heat up more because of the BEC and that's the last thing you need. Think of it this way, running 4s on the built-in BEC with a 1A load will force the ESC to dissipate over 9 watts. That's really a lot.
