Can you remove the name "Summoner's Rift" from the main game?

Honestly, I don't understand why the original lore for the game was completely scrapped. Like, everything about it was absolutely fine. It made sense. In order to hold some type of relative peace between the nations, they would hold wars on the Rift, allowing Summoners to take control of their actions, which is why the main map was called, "Summoner's Rift" because of the summoners. Which is why some characters would interact with them. It wasn't just a little joke of them breaking the fourth wall, they were 100% aware of the Summoner's controlling them.

Just the fact that some of them were just flat out against the idea, where others were doubtful of the Summoner being able to control them properly.

Miss Fortune: -Are you sure you can handle me, Summoner?

Nidalee: -You cannot cage me, Summoner.

Mundo: -Mundo will go where he pleases!

-Most of Morde's lines.

But now, the entire idea and reason for them to be on the Rift is gone. There is no Rift anymore. Or any Summoners. So... it just seems kinda pointless to keep the name of something that doesn't exist! Perhaps something a bit more appropriate to what's going on. Like maybe, "Champion's Arena." Or.... "Champion's Rift." Or something like that. :o
