Morphology
The meaning 'an imaginary or marked boundary beyond which there is danger' is directly and transparently derived from combining 'danger' (risk of harm) with 'line' (a boundary or mark). This compositional pattern (a line marking danger) is straightforward and cross-linguistically common, so a B1 learner who knows both words would readily infer the MWE's meaning.
Etymology
The noun danger line comes from a simple image: a line painted or marked where danger begins, like on a pool floor or a ship deck. So, it means the boundary or limit you should not cross because of 'risk'.
