In my understanding, though the name reveal serves no purpose in the story of the game, it does serve a purpose in making, for the player, an analogy.

Possibly the main theme of Undertale is learning to be a better person than you thought you could be (through the Pacifist route especially). By associating the player with Chara (through the shared name), who took for granted their role as an evil (evidenced especially in the post-Genocide monologue), Undertale makes you think, at least to an extent, that you too are limited to a certain role. However, upon completing a Pacifist run, you begin to realize that you can be a better person – you don't have to kill to succeed, being truly kind is possible – and, at the same time, you learn that you aren't playing as Chara, but as Frisk. Although this isn't a revelation for any of the characters of the game, it is a revelation for the player: you aren't doomed to be what Chara represents. Chara isn't you, and although you can make yourself Chara (through Genocide), it isn't necessarily your destiny, because now, you're Frisk.

Hope that makes sense.
