I'm building a Rc car and I have the arduino Uno. I had quetion if I could power the dc motor up to 15V (connected adfruit Motor shield), what dose it mean that the Arduino can only operate with 5v?

The motor voltage does not power the Arduino. So, yes, you can use 15V for the motors (if they can take it).
The Arduino operates at 5V. The power supply can he higher. The voltage regulator will waste the excess (as heat).
