Refer to the spec, most notably the forbidden contents (in the SGML definition; for assistance reading that, look here): as, forms, form "controls" (input, select, etc), and fieldsets.

While you are correct in asserting that spans (and divs, etc) are legal contents of a button element, the illegal elements are all to do with having button content that does anything other than layout / styling.

I don't see anything in the spec precluding what you're trying to do, but I do see a lot discouraging it, and would be unsurprised if various browsers also "discouraged" that by not supporting it.

Which is to say: find another way to do what you want if you want to have cross-browser support. I don't understand what you're actually trying to do, so I don't think its possible to propose alternatives. I get that you want to respond differently to clicking on the button vs the icon -- but that's a (good, btw) demonstration of what you don't want to happen, not an explanation of an actual problem you want to solve.

One way might be to not use a button, and instead use another span or a div:
