Yes, but the export in itself will only create a W3D file with no interaction built into it. You will have to use Macromedia Director to create the interactivity, and to set the cartoon-shading on the models manually (through code) that need it. You will also have to program functionality such as walking and looking around.
You said Sketch and toon, what do you mean by that? A pre-rendered background with the sketch and toon renderer? ShockWave has support for realtime toonshading if you should choose to use that. If not, just create a spherical or cubical skybox.
If you need help with the technical side I might be able to help you out.
This is a walkthrough I have programmed before:
You might have to click inside the 3D view to enable the arrowkeys (use arrowkeys on your keyboard to move).
