Quoted relevant block again as you’ve only read the part that addresses when you want to purchase WoW tokens, not when you already have them.
“If you have run out of Game Time you cannot interact with the WoW Token system in WoW Classic Progression; you must consume your Token while you still have active Game Time on your account and you can only use the Token on the same account on which the Token was purchased for gold.”

Etc etc, there’s precedent for them denying such requests and I’m only setting your expectations here fair and without bias. What you do is your own responsibility.
