 No. Search for KDE_FULL_SESSION in 
http://websvn.kde.org/*checkout*/trunk/KDE/kdebase/workspace/startkde.cmake .

 This is only up to your application - when session saving, applications tell 
the session manager the command to be used for restoring, and that's exactly 
the command the session manager will use.

 You might be also interested in 
http://websvn.kde.org/trunk/KDE/kdebase/runtime/kcontrol/componentchooser/windowmanagers/ - 
KDE session manager has special support for launching window managers (in 
order to ensure they are the first to be launched, etc.). The window manager 
to be used by KDE is configured in systemsettings->Default applications and 
such a file is needed to be listed there (needs to be installed in 
<data>/ksmserver/windowmanagers, where <data> is from "kde4-config --path 
data").
