Not currently.  The best thing you can do now is check against the WP  
version number, or maybe check for the existence of a function that  
was introduced in the same version that the hook you want was  
introduced.  I've proposed a function for checking for the existence  
of WP core hooks.  The idea has been given a relatively lukewarm  
reception.  If this is something the devs would put in, I'd gladly  
code it, as I am already up to my elbows in hooks with http:// 
wphooks.flatearth.org/
