Morphology
The meaning is directly compositional: 'charter' (a founding or establishing document) + 'member' yields someone associated with that founding document, i.e., an original or founding member. This reflects a straightforward adjective-noun/attributive relationship found across languages, so a B1 learner who knows both words can reliably infer the MWE meaning.
Etymology
The term charter member comes from the old practice of writing the names of the first members on a charter, a formal paper that created a group. Those named members were the original people who started the group, so 'charter member' means 'one of the founding members'.
