No, like an Uno has no means to read a thermistor or drive a heater. You need additional hardware.

Nitpick, but neither does a MEGA2560 or any other setup that uses a shield-like board plugged into an Arduino (or similar microcontroller). You're always going to need additional circuitry of some type, whether that's on a shield or built into a all-in-one board.
