Sorry Frank, but I'm really not sure where you are getting this from... In fact, you said it yourself, CAN is a two-wire BUS. Daisy chaining is just an easy method to accomplish it. There is nothing stopping you from putting terminating resistors at each one of your end points and then running everything back to a central hub rather than daisy chaining.
To my knowledge (and I haven't looked at all of the ISO standards and heaven only knows I could be wrong) there is nothing prohibiting the use of a star topology with a CAN network rather than a daisy chain topology.
