The 130V is capacitive pick up as live and switch live un adjacent, and is only seen because your meter is high impedance - if yo upit a test lamp accross it it will not light but the volts will diassapear.
As others have said nicking a live feed from another circuit from which neutral is taken is naughty, but there is nothing to stop you haveing a two gang switch with oppposite sides on different circuits, most hall-landing switches are like this .
The thing is to have 2 gang switch at the kitchen door, one side normally wired to the ceiling light, and the switch cable to the other side running reasonably obviously to the cupboard lights. This can then be supplied from any lighting circuit or a fuse spur, or even from a dedicated MCB straight from the consumer unit - it matters not. Many wall lights are done this way, and its not considered surprising the wall lights are on the ring, and the ceiling lights are on the 'lighting fuse'.
Not too bad, until the supply is 3 phase, and you find 400v between lives on a double switch.
What you want to avoid is the borrowed neutral scenario, where it is possible to be working on one circuit isolated, but find (painfully) that it is still carrying return current from another circuit not isolated.
