noname=yes can be used to mark the absence of a name i.e. where something really does not have a name in reality. This is to distinguish it from the situation where the name=* tag is missing due to incomplete OpenStreetMap data. Missing name=* tag is a common situation, caused by for example sketching over aerial imagery.
This tag was discussed as one of several alternatives under discussion at Proposed features/Noname. Nowadays it has a widespread usage and is used by multiple validators and OSM editors.
