Morphology
The expression relies on a physical-support metaphor: knowing 'no', 'leg', 'stand', and 'on' allows a learner to infer a lack of support or footing, so a B1 learner could guess the general idea of having no support. However, mapping that concrete image to the more specific abstract meaning 'no valid reason/justification' is metaphorical and partly idiomatic, so the relation is not fully predictable without some exposure.
Etymology
The idiom no leg to stand on comes from a simple image: if something has no leg to stand on, it cannot stay upright or be supported. So the phrase means 'to have no support or good reason'.
