In the sense that if its computed display is "block" but its layout 
behavior is not that of a non-replaced block (CSS 2.1 section 10.3.3 and 
so forth), then it's clearly a replaced element with layout behavior 
defined by something other than CSS.

Sure doesn't seem to be, since no UA actually renders <button 
style="display: block"> the way a CSS block renders; they do something 
totally different which is presumably covered by some other spec (e.g. 
HTML).
