Are Charon and Planet X the same planet?

No they are not. Chiron is a real object in the outer solar system, formerly called Kowal's Object. This is not to be confused with the satellite of Pluto called Charon...which I routinely do!!

For more information on Chiron see the NASA web page, which I excerpt below:

On February 14, 1996, the enigmatic object Chiron reached perihelion inside the orbit of Saturn and on April 1 will reach perihelion opposition, its closest approach to Earth. Chiron is unusual because it has a detectable coma, indicating that it is a cometary body, but it is over 50,000 times the characteristic volume of a comet, a size more commensurate with a large asteroid, which it was initially assumed to be. Furthermore, its curious orbit is unstable on time scales of a million years, indicating that it hasn't been in its present orbit long. Chiron was the first of four bodies discovered so far with similar orbits and properties. These bodies have been designated Centaurs, after the race of half-man/half-horse beings from Greek mythology, in recognition of their dual comet/asteroid nature. (Chiron is named after the wisest of the Centaurs, the tutor of Achilles and Hercules.) It is believed that the Centaurs may be objects which have escaped from the Kuiper belt, a disk of objects orbiting beyond Neptune. Chiron is showing increased activity as it approaches perihelion. In an effort to coordinate observations and gain an unprecedented view of a possible Kuiper belt body, the Chiron Perihelion Campaign was organized. This page contains information on Chiron and the campaign to observe its perihelion passage as well as links to images of Chiron from various sources.

Planet X is a hypothetical trans-Plutonian body of planetary size. There are no known bodies that have ever filled the slot of a 'Planet X' despite many careful searches over the decades.
