The answer is no. There are certain unaccessible areas like in the caged area in Varrock bank and the islands near the champions guild that no one has ever walked on and possibly never will (Unless Jagex decides it would be fun to make a quest where you could finally lock-pick that stupid gate ...).
Those squares are unwalkable. The question is regarding walkable squares.
I'm not entirely sure. There are many areas all over the place that people tend to just walk through without stepping on every square, but then again a lot of those squares probably have been walked on to kill monsters and get items and stuff.
I'm going to say yes. Despite the fact some squares have an incredibly low likelihood of being walked on, there are a large number of players in the game. Some monsters dwell in strange places to be sought out by people. Some clans hold meetings in strange places. With the number of players in RuneScape, the likelihood of every square having been walked on is probably quite close to 1.
