Linked wrong steam account

Hi, my friend has linked his old steam account instead of his new one so even when set to public FAF will not pick up his copy of the game.

Can he switch his linked account?

*Edit: spelling

If there was no Forged Alliance in the account the linking was canceled and he can just try again with the new one.

@brutus5000 thank you I'll get him to give it a go
