Should the account name be exactly the same name used in W-8BEN tax form?

Hello contributors, 

I have recently changed my account name 'first and second name',

The old name was a nickname I used, I previously filled the W-8BEN tax form with the nickname and it was accepted.

That WAS the case with all previous withdrawals I did.

After changing the account name, should I refill the form with the new name?

*The old tax form is still valid for 2027, also when I changed the name there was a payout request which were already in review, and it was accepted despite the difference between old name in the tax form and the new name.
