No, currently Delphox cannot Mega Evolve or evolve into any other form.
Delphox is #655 in the national pokedex, and it is a Fire-Psychic type Pokemon.
In a battle, Charizard has a type advantage over Delphox due to its Fire/Flying typing versus Delphox's Fire/Psychic typing. Charizard's Flying-type moves can effectively counter Delphox, while Delphox's Psychic-type moves are not super effective against Charizard. However, the outcome can depend on level, strategy, and movesets, as well as the presence of items or abilities. Generally speaking, Charizard is likely to have the upper hand in a direct matchup.
