Do you need to? This is valid as an entire Org file, I think:

*** foo
* bar
***** baz

And that can be represented in EBNF. I'm not aware of places where behavior is indent-level specific, except inline tasks, and that edge case can be represented.

list ::= ('+' string newline)+ sublist?
sublist ::= (indent list)+

I think this captures lists?

Definitely not able to be represented in EBNF, unless as you say {name} is a limited vocabulary.
