Reporter gene is one that is inserted to different researcher-made genetic structures (e.g. enhancer trap).
Reporter gene is frequently used to check if some gene without detectable product is expressed. For this reporter gene codes for easily detectable product.

Marker gene is just a genetic marker (like VNTR or RLFP) that can be detected for genomic mapping. Marker gene is usually not artificial.

I think reporter gene that you use for mapping could be called marker gene.
Thus, the defintion is operational one.
