Some laptops do have replaceable cpu's, others don't like maxalge stated. Since you asked about intel hd graphics you're using an intel system. In order to use amd you'd have to have an amd motherboard and an amd processor. That's not possible on a laptop, you can't just swap parts freely like you can on a desktop. If you want an amd based laptop you'd need to buy one that's built with an amd system inside it from the start.
