I don't think "Interest Only" is a triggering term. We don't have the length of the interest only period, an example of how much a payment may be, or even the rate itself.
But to answer question of a triggering term in the name of the product - I would argue heavily that if this product is printed on a banner, billboard, flyer, etc, then the name itself IS an advertisement. After all, that is the purpose of the name, right? To grab your customers' or potential customers' attention.
