This is beyond my experience. At some point I expect they'll find out the old name, but the only time I know you'll be obliged to include the corporate name will be on a contract, and if they've got to the point of signing a contract with you, then I doubt it'll be an issue. However, someone else will be able to give you a more certain answer than I can. I don't know why you're so concerned about your corporate name, but if it's something really weird, or something totally antithetical to the product you're selling, you might rehearse a clever and self-deprecating answer. Maybe even something as simple as, "yeah, we pivoted. Obviously", in the right tone of voice, will dispel questions.
