Morphology
The meaning is directly compositional: 'cough' (expel air from the throat) + the particle 'up' (bringing something out) + 'hairball' (a mass of hair) clearly yields 'expel a hairball from the mouth'. This follows a common English phrasal-verb pattern with a literal physical image that a B1 learner who knows the constituents can readily infer.
Etymology
Cough up a hairball shows a simple picture: a cat coughs and pushes a small ball of fur out of its mouth. The parts cough up and hairball name the action and the object, so the phrase means 'to bring up a hairball'.
