What kind of caging are you using for the button quail now? I wouldn't think that one would be happy in a traditional bird cage, what with their tendency to jump high when startled.
If your linnie is in a large, walk-in aviary, I don't see the harm... although be mindful that linnie beaks could cause some damage to a tiny button quail.
