Do NOT use carpet underlay for laminate. Laminate underlay comes in two basic forms, fibre boards, or foam. Laminate underlay is designed to allow a certain amount of flexing, importantly they are also designed to help prevent "drumming" which is the noise you make walking over the laminate. Carpet underaly is designed to add spring, which will break the joints on laminate. Always use foam underlay as you can bring it up the wall by 15mm as recommended. This helps prevent any damp ingressing into the laminate boards.
