Yes you could. My understanding from it is that a trademark is only valid for a certain category of "products", which also applies to company names. For example, if you make a company that sell apple juice, and you choose to call it "Apple", because you're not selling the same category of products as "Apple" which sells computers, it's allowed.
I would find strange that you could call a company selling computers "MacBook" though, but technically it's a shop vs a computer, so not the same kind of thing.
And I think this article is confusing, because it's not "Big Mac" that this restaurant is called. It's "Supermac", which isn't exactly the trademarked name. Maybe it would have been different for a "Big Mac" hamburger restaurant.
