One possibility that would suggest a connection: During the tutorial, our male protagonist is not actively serving, in spite of there being an ongoing conflict. Let's assume that he was stationed in Alaska as part of the US Marine Corps, but was injured during some particularly heroic deed. He is given honorable discharge due to his injuries, and near the end of his recovery period, he and his wife (formerly serving in the US Navy as a logistics officer) relocate to Massachusetts. This is partly due to the recent addition of their newborn son, and their desire to make a fresh start. The Sanctuary Hills site has been recently developed, and is made available exclusively to qualifying army and Navy veterans (this would tie in with Vault-Tec, as well as the pre-war tutorial).
Going back to Maxson, due to his senior position and clearance level, he learns of our protagonist and his heroic actions during service (Maxson may well have had close ties to the senior commanding officer in charge of operations during the Alaska conflict). He decides to keep a close eye on our protagonist, and even pushes through a 'recommendation' for him to be assigned to a top secret project in Massachusetts, hence the reason our protagonist and family are given the opportunity to relocate to Sanctuary Hills, which is part of the site for vault 111. This could later be incorporated into gameplay when we meet Arthur Maxson during the main quest, and we learn of his ancestor's connection to the Alaska conflict.
Note that this would also explain the flag display case (which can be awarded to living veterans), as well as the forthcoming speech at the Veteran's Hall.
EDIT: tl;dr Maxson could have known of our protagonist in connection with the Alaska conflict.
