All Game of Thrones Virtual Challenge join codes will have an expiry date which is 2 years from the date of purchase.
This means that the join code must be redeemed within 2 years. Regardless of when the redemption occurs (inside the first 2 years) an active virtual challenge will remain active for 24 months before expiring.
So from when you purchase the challenge it is possible to completing this challenge and redeeming your medal after 4 years at maximum (assuming you waited as long as possible to redeem and complete the challenge)
Please note that adding the join codes to the My Join Codes screen in the app does not have any affect on the timeframes quoted above.
