Morphology
The meaning (to behave in a role or pretend to be something) is directly built from 'act' (to behave) plus 'as' (in the capacity/role of), so the overall sense is compositionally predictable. This role-marking use of 'as' is common in English and parallels patterns in many languages, so a B1 learner who knows the constituents should be able to infer the MWE meaning.
Etymology
Act as comes from the idea of an actor on stage who plays a role. When something 'acts as' a tool or leader it takes that job, so the phrase means 'to serve' or 'to function'.
