To my understanding, Leisure Farm's location is well within Iskandar region.
Just that it is not part of the UEM/SP Setia owned land, which covers East Ledang, Ledang Heights, Puteri Harbour.
It should be located within Zone B of the Iskandar Development Region, which covers the broad Nusajaya region.
Yes LF is located within the Iskandar region in zone B. much of zone b belongs to UEM who sold land to other developers. But LF belongs to Mulpha and has been for the past 20 plus years. So LF usually not mentioned cos competitor of UEM.
