Opened AMEX Delta SkyMiles Gold personal instead of business

Am I screwed if I want to use this the AMEX Skymiles Gold Personal as a Business card for my business? I planned to use this for business flying and general purchases, but realized that it was for personal and not business once all complete. Pretty sure I can't switch them, but instead open a second. Luckily I can just cancel in a year without a fee, but woops!
