Well, if something as... well, random, as Jimminy's Journal can have a physical manifestation, then why not Kingdom Hearts? I highly doubt that the Mysterious Figure is, however, since we're only at the tail end of the first saga in a "much larger series."
Because everything has been/can be called the physical manifestation of KH. Sora has been called that, Kairi has been called that, <insert armored/cloaked/silhouette character> has been called that.
No claim of "X is Kingdom Hearts" has any real basis behind it, it's just a random claim thrown out there.
