Yes, but it probably wouldn't be published. At least, not in modern times. Historically letters to the editor were written anonymously or pseudonymously. They were essentially op-eds before newspapers had op-ed pages; think "Letter from a Connecticut Farmer", Silence Dogood, the Federalist Papers. During the 20th century, however, a strong tradition developed of only publishing letters written with real names. Addresses, too; the author's home town was usually included, and comic books usually printed complete addresses.
