No, you cannot. But you could use a functor, that is a class with operator(), 
instead of a function.

class Cube_functor {
public:
  Cube_functor(double x0,double y0,double z0,double r0);

  double operator()(double x, double y, double z) const;
};

Then you can create a functor object with the right parameters:

  Cube_functor my_cube(0.5, 0.5, 0.5, 0.5);

and use it as a function. Mesh_3 implicit domains can deal with a functor.
