So can you use the name of a company on your domain? The answer is yes, as long as consumers and people in general, upon seeing your domain or visiting your site, won’t be confused and assume the site is an official one, or that it’s in some way related to the company.
For instance, there’s a site called AppleInsider.com, which covers all things Apple. Apple is a registered trademark, but they can use it because the domain makes it clear that it’s a news site and not related to Apple Inc. in any way.
I can use any domain as long as it's not misleading. so, if I was to create a site about tattoo designs and use the domain. It isn't illegal.
