Morphology
The phrase maps directly from the literal 'shim' (a thin piece added to make parts fit) combined with 'add', so a learner who knows those words can infer the idea of inserting a small element to make things work. However, the computing sense (a small compatibility layer of software) is a technical, metaphorical extension of the physical object and requires domain knowledge, so the relation is only partly predictable without exposure.
Etymology
Add a shim in software borrows the same picture: programmers put a tiny piece of code, like a thin shim, between old parts and a new system so they fit together. So, add a shim in computing means 'to add a small fix' or 'to make old software work' as a temporary solution.
