I have a typical 30" stove installed in the center of a 20' wall with a standard overhead hood that looks a lot like this.
I want to redesign my kitchen with new cabinets so the stove becomes corner mounted (45 angle) which means moving the stove about 9 feet along the wall (towards the center of the house) into the corner so it would look like this.
Is there any reason other than maybe local (Los Angeles County) codes (I haven't checked yet) that I couldn't or shouldn't reroute the hood ("flue" ?) pipe at an angle so it meets the existing roof vent from the new "starting" position instead of a straight vertical pipe?

Putting the stove in the corner like you propose also gives you some nice space to work with for routing the pipe up into the ceiling / roof area or out an exerior wall.
Seems to me that re-routing the vent to the previous riser location is a total non-starter. Many hoods vent up into the small cabinet above the hood and your re-routed vent pipe is going to make a mess of the upper cabinets if it has to route nine feet across your kitchen.
