Sort of, see _NET_WORKAREA in the EWMH specs
http://standards.freedesktop.org/wm-spec/wm-spec-1.3.html
But if you window has decorations, you cannot use it directly
to calculate the maximized size and position.

No.

What `maximized window' means is defined by the window
manager and windows are maximized by asking the window
manager to do it.  Some window managers even may not support
maximization or may have it intentionally disabled.  The
right size and position can change over time (desktop is
resized, bars are shown/hidden/resized, ...).
