Actually even KQ2, KQ3 and KQ6 can be divided into chapters.
KQ2 is fairly obvious, three splits at the magic door, with the search for the three keys, and then the travel to the enchanted realm.
KQ3 has several linear 'chapter-like' sections, Llewdor, the pirate ship, the beach and mountains, and finally Daventry and Cloud Land.
KQ6 had hidden chapter triggers (as the developers described it), certain actions opened up new areas in the game locked out others. The earliest for example is obtaining the magic map, triggers the nightingale and partial access to the islands. These 'chapters' are seamless so the player's don't realize they unlocked the next portion of the game.
Even KQ8 is more or less chapter based with it's linear progression. There are only a couple of puzzles/side quests that require back tracking!
