Yes...
...IF you're asking if there's a RAW way for someone to survive inside a Bag of Holding for longer than 10 minutes. If you're asking if it's possible to make a livable environment inside the Bag, then the answer is 'Not by RAW'.
While there is no RAW 'Create Air' spell, there is a Necklace of Adaptation. Its description says
While wearing this necklace, you can breathe normally in any environment...
In practice, it'd really have to be up to your DM of course. The full text of the Necklace implies that it works to safeguard one against things added to an already breathable environment like poison gases, etc.
However, the text does say 'any environment', so a RAW interpretation would mean literally any environment.
