Does Using “The” in a brand name improve it?

Never thought much about it. Pubs are very often called "The" something. I think that's because of the sign they used, like "The King's Head". If someone said "I will meet you in King's Head" I would imagine it to be a place. Interesting.

I think we are in urgent need of an etymologist.

This article argues for it.

"The most commonly-used word in English might only have three letters – but it packs a punch."

It makes sense since "The" imbues importance to any word. A word gets power in people's mind once "The" is used.
