It's worth wondering if someone can simply get a PO Box at a downtown Post Office and get bumped up the results by virtue of your business mailing address.

You wouldn't want to use a PO Box. You'd want a maildrop street address.

You'd also need to be consistent across the entire web, because Google can easily compare data. Even unintentional inconsistencies can cause listing problems, so for local you want to "cleanse" your data, as it's called. There are services that do this.

If the maildrop address is fake and you have an actual physical presence somewhere else, then you create another problem for yourself... ie, your customers won't be able to find you via the web.
