Yes, you can do something like that, in fact many start-ups do use falsely inflated "trade lines" to build up business credit. The drawback is that at some point D&B will want to see audited financial data from the companies involved...at that point, if you send in fake balance sheets and what not you are perpetuating fraud...if you default on any of you loans or credit lines, this can come back to haunt you in the form of lawsuits, and possible bank fraud. Still think it's a good idea?

I'm not saying not to do it, but I'm just pointing out the risks.
