Noodle is broader in a different way, because it can refer to Asian wheat or rice strands as well as some pasta shapes in informal speech. Penne is closer, since it is also a short tube pasta, but penne is usually larger and cut diagonally. Elbow macaroni is the especially common curved form people often use in macaroni and cheese. If a recipe says pasta, many shapes may work. If it says macaroni, the writer usually wants that small tube shape.
Etymology
English borrowed macaroni from Italian maccheroni, the name of a tubular pasta. In eighteenth-century Britain, the word was later used jokingly for fashionable young men who returned from Continental travel with exaggerated foreign tastes and clothes.
