Have the space, don't want to use the domain

Hi, there!
I’ve bought a domain (www.domainbought.com) + 15gb space at one.com. I’m currently installing wordpress via Filezilla.

Is it possible to use the space I’ve bought with a different domain? Example: use the space from https://www.domainbought.com on exampleblog.wordpress.com ?

Thank you ??
