Sorry, not sure what Apple would do about it. You wouldn't be able to replace it with a new machine [under ADC] anyway, until you renewed for the following year (you're limited to one unit per year). If you're planning to renew, you might be risking the ability to do so. The agreement doesn't say what remidies Apple can get if you violate that part of the Agreement, but I can't imagine it would be more than the discount itself. But, that's just an opinion.
