I recently gave interviews for Meta, and cleared them. Recruiter said they want to move forward with me.

The location I gave the interview for is Toronto, Canada. But I want to change the location to London, UK.

1. Can I do that?
2. If yes, what should I tell the recruiter?
3. Will I receive pushback from the recruiter?
4. Will it negatively affect my chances of negotiating the offer? (I feel I did quite well in the interviews)
