@earlfurman T2Laser supports PLT (HPGL) format which is similar. It would not be that difficult to convert Turtle Graphics to G-code but you would still need a "sender" to get the code to the machine correctly. You could use T2Laser or something like GrblController for that but it wouldn't be an integrated solution.
What is the reason for wanting to use Turtle Graphics rather than draw in Inkscape (which can run python scripts) or a similar program and then export the result as DXF which can already be loaded and sent to the machine with T2Laser or other software?
