Not really, no.  There is 'Macro' (which I think used to be called 'Function'), but no.

But there is the Gmsh API which can be used instead of writing a GEO file

Before that came along, the best approach was generating the GEO file in an external script, e.g. Python.  A formalization of this which I still use myself is pygmsh.
