Yes.

asmx code call the controller and have the controller return data to the .asmx code?

Yes.

var controller = new YourController();
var httpContext = new HttpContextWrapper(this.Context);
var routeData = new RouteData();
var requestContext = new RequestContext(httpContext, routeData);
controller.ControllerContext = new ControllerContext(requestContext, controller);

var result = controller.YourAction();

But I discourage to do that. Instead move common logic into a separate service layer and use that one.
