Nothing automatic about it but you could use system-config-network to 
create multiple network profiles, one in which wireless is active, and 
the other in which the wired ethernet is active.  Then use the 
"netprofile=aProfile" kernel argument at boot to select the profile you 
need.  The latter can become grub boot menu choices by duplicating the 
lines for the default boot in /boot/grub/grub.conf, then adding the 
netprofile= setting to the end of the kernel line in each (using 
different profile names) and changing the names of the two boot entries 
accordingly.
