I resoundingly agree with Harry Johnston's explanation.

In-universe, it's most accurate to say that Aslan is the Narnian expression/ incarnation/ avatar of the same creating, teaching, guiding force that Jesu is the Earth Christian expression of. And that Krishna is the Earth Hindu expression of. Etc.

Oh and more philosophically, Tash was the Calormen name for the same force, EXCEPT only to the truly faithful, just, kind, charitable, etc. Recall that in The Last Battle, Aslan states that those who worship Tash with good deeds are really honoring Aslan, and those doing evil in Aslan's name only empower Tash. This shows that the force Aslan embodies in Narnia is recognized by many cultures and may validly be called by other names.

This is similar, but NOT the same as a multi faith leader saying "those who call it God or Allah are honoring the same thing, as long as they are not violent and destructive, because that just invokes Satan." And note this applies to Cristian crusader terrorists as well as Muslim dissident terrorists, or to anyone else. But it was not exactly meant to be an allegory, it's just a fictional culture that is very superficially similar to the classic Western impression of the Islamic world as completely harsh and foreign. Just a sort of off the cuff, invented, not carefully representative world.

Also I got the firm impression in The Magician's Nephew that Aslan knew all about Jadis' world of Charn (if I recall the name) because the same goodness force (but not exactly "Aslan") had once held influence there. The statues of ancient rulers looked benevolent and wise. Janis has never heard the name Aslan, but she recognizes his character archetype of powerful governing creator.

One more point: Father Christmas shows up in Narnia. WTF. He's not a Narnian version similar to Father Christmas, he is literally THE Santa reindeer-driving Claus. If Lewis did something that blatant, then he could have put Jesu directly into Narnia if he wanted to. He did not, because Aslan is Aslan. Even if he represents the same exact role of power and sentiment that Christians describe as The Christ.

Yes Lewis was Christian. Yes he was also very intellectual and that apparently gave him trouble with the less logical or sensible specifics of that particular faith. He held a religious and philosophical outlook which led him to write these stories as a sort of thought-experiment. He wrote up, without really planning it carefully, a multiverse cosmology in which other worlds exist (for instance Narnia), and he figured that, since Christianity sees our daily life as a temporary prelude to the "more real" afterlife, these other worlds would be no more or less real than our own Earth. So Jesu is no more or less real than Aslan.
