Not in general, since most apache directives are resolved at
start-time, not at request time.  But in that particular case, you can
use mod_rewrite:
RewriteEngine On
RewriteRule ^/documents /home/www/%{SERVER_NAME}/documents
(You probably want to assure that UseCanonicalName is set On in this
case to avoid bad things happening when people supply arbitrary Host
headers.)
