No.
EASA has no power to revoke licences. World aviation is regulated by the ICAO. There are 192 ICAO member states, and EASA is not on the list. EASA does not issue licences, it is merely a club. They set standards higher than ICAO, and members agree to recognize each other’s licences as they would their own. The only thing that EASA can do is refuse to recognize a CAA licence as an EASA licence. Member states are required by the Chicago convention to recognize ICAO licences, EASA or not.
As long as you are flying a G-registered aircraft, a CAA licence is valid anywhere in the world, including Europe.
