No, a heavier bullet necessitates a reduction in charge to keep the pressure the same as the lighter bullet.

The proper load data is avalible on the Hogdon powder website: http://www.hodgdonreloading.com/data/rifle

Select "22 hornet", then "40 grains" then "lil gun".

scroll to the bottom for lil gun!

I have found personally the charge i use for 35 gr v max is also the best charge for 40 gr bullets but is seat them 15 thou longer, but as you're upping the weight i'd back off half to one grain and work up again to make sure the load is safe and also that you don't miss an accuracy node.

Edit: I've just noted you're using 12 gr under the 35s, this is minimum load anyway so start there and see how you get on, you may want to seat longer and you may want to get closer to the max (won't publish my load but its a lot higher than 12!)
