Theoretically, this is not a problem. If you have a large wall which emits light uniformly in all directions (https://en.wikipedia.org/wiki/Lambertian_reflectance), the *distance* doesn't matter. But in practice, I believe that it is very tricky to do this right, and even more so to validate it. Especially stray light is difficult to manage.
