No - the moon is the chronocator of the chart, and also a kind of floating co-significator. Some people assign it to the querent specifically, but I don't think it's that fixed, though that's a matter of opinion.

If it's making a good aspect to the querent's planet it should be a help in any event, and depending on the dignities, it might also be translating light from querent to quesited, or vice-versa.
