No - stain, whether water based or spirit based, will penetrate into the wood, and when it's in, it's in. The same applies to oil based finishes such as Danish oil, tung oil, teak oil etc.

Toner (as with lacquer) 'sits' on the wood, so if sanded back (judiciously!) will be removed, as will be the lacquer. That's why so many 'Ovaltiny' radios have been trashed when the two toner bands have been stripped off with the lacquer. If anyone attempted to replace the darker bands with stain rather than toner, even if masked off, the stain would creep along the grain of the veneer beneath the masking tape, whereas toner wouldn't.

The best way to sum it up is that with stain, the colour is in the wood - with toner, the colour is in the toner.

Sometimes, toner can be a hindrance on items which are handled a lot such as guitars for example, because if the lacquer is scratched or worn away in use, if toner is under the lacquer, that too will be removed.

Hope that helps.
