Hi
You can carry both Laptop in one bag, I always carry two laptops one official and another personnel while travelling from India to Doha – Doha to India,

Please note sometimes Emirate airlines check cabin bag weight plus laptop bag ,it should not exceed 10 KG (7 KG Cabin + 3 KG Laptop)
Whereas most of the time Jet Airways dont even check cabin bag weight
As it is a new laptop dont carry it in carton box instead place both laptop in one single laptop bag, charger can be adjusted in Luggage bag.

Happy Journey
