There should be a function to create a point from lat, Lon but I do not see it in the function list. It is a little to do anything other than transform the main geometry - since often the data is queried using a BBOX against the main geometry.
For greater control I would recommend use the centroid as a staring location, and provide an offset to determine the label position. The offset can be expressed as an expression which you can adjust for scale.
