The leap that a narrator is an unreliable narrator is a huge one and one I wouldn't make unless the narrator is demonstrably unreliable like, say, The Usual Suspects. It's clear in both the Mad Max movies and the comics that the narrator exists only to establish a setting. There are few stories that actually hold up to the scrutiny of being a tale told to someone else. Do you honestly watch Fury Road and picture Max describing all the events to someone Princess Bride-style just because there's a bit of voiceover at the beginning? Obviously not.
It's not so much a leap as imagining Max had plastic surgery to become Hardy.
Mad Max 2, for example, was a story told by the narrator who, at the end, says,
Narrator: And the Road Warrior? That was the last we ever saw of him. He lives now... only in my memories.
In
Thunderdome Savannah narrates the ending.
I've found a few Australian films tend to have a surreal quality, like
Walkabout,
Razorback,
The Cars That Ate Paris, and so on. There is a little of this quality in the
Mad Max series, that leads me to see them as not completely literal. But as legends.
Miller was cagey about how
Fury Road fitted in.
George Miller said:
It’s sort of a revisit. The [previous] three films exist in no real clear chronology, because they were always conceived as different films.
And Tom Hardy's view:
We have to take it differently as George is taking it. It’s a relaunch and revisit to the world. An entire restructuring. That’s not to say that it’s not picking up or leaving off from the Mad Max you know already, but it’s a nice re-take on the entire world using the same character, depositing him in the same world but bringing him up to date by 30 years.

The analogy on that site was, "James Bond", which is a more difficult conundrum if you wanted to rationalize Ian Fleming's character with the films.
Sometimes I just have to find a way to make films work to really appreciate them, and when it comes to the behemoth that is
Star Wars, just throw out whole chunks of the 'official' canon.
But I digress, because the main event is that VTS is finally getting their figures out the door soon...
