I'm due to perform the 1st service soon. Is 15nm pre-tighten and 42nm final-tighten the correct torque for the valve lash nut?

NO!!!!!. That sounds like the torque values for the actual head.
Do not try and torque the valve adjustment lock nut. Just needs to be wrench tight.
Rocker lash locknut is no more than 6ftlbs, I do 5.5 all equal works the best. I push on rocker to squeeze out oil w/measuring. If you use anti seize wipe off all excess, I don't use it much.

Because sometimes people just want to have some fun.....by the way, my Suzuki VStrom does not have any so that is of no help........
But my Stelvio....it's 8mm......and again, I would not worry about torquing it. Just needs to be wrench tight. When you get that low on a torque spec the chances of over torquing increases unless the nut is completely dry and your wrench is calibrated in that range. Also, when you are tightening the locking nut, you want to hold the adjuster screw in place so it does not move while tightening or you will be chasing your tail to get the right gap. Can't do that with a socket on it.
Just my experience so take it for what it is.
I find that on some fasteners like this one or spark plugs, valve covers and so on. You have to forget the torque wrench and use common sense tightness and the feel of the wrench in your hand.I was going to try to find an 8mm fitting for my Tusk spoke torque wrench which is calibrated in inch pounds (30 - 150) since it works from a side attack like a wrench. That would leave the adjuster screw accessible and enable application of a known value for tightening the nut.
But I can't find any 8mm fittings for the Tusk.
