It can with a remote trigger available from several manufactures.
One of which is Canon. The Canon transmitter costs $280 at B&H. But the 430EX III-RT, which includes a radio receiver, is on sale for $260. And your 600EX-RT can serve as a transmitter, even if you have its flash head turned off. Which would give you the flexibility of two radio-capable flash units. There may be a no-brainer lurking in there somewhere.
There are no Canon camera models that have a built-in radio master that can control a flash. Controlling a 600EX-RT via radio requires a radio transmitter such as:
1) The ST-E3-RT transmitter
2) Another 600EX-RT mounted on-camera and put it master mode, or
3) A 430EX III-RT mounted on-camera and in master mode.
You can trigger the 600EX-RT in "optical" mode using the pop-up flash on the T5i.
