Yep! 

You can also unlink all auth methods then link the new node, but it’s dangerous, so I’d recommend the path you describe instead.

So I suppose, with another temporary linked auth, I can unlink the LNURL (from a dead node) then once I have again a good LNURL auth I can re-link it to the account.

SN release: multiple auth methods for a single account

Thanks man! This is great news!
I will try it out.

EDIT: Works perfect!
