Yes, it does use the same kernel. If you read the jail(8)
man page, it discusses setting up a jail on a 4.x system.
The first section contains
This example shows how to setup a jail directory tree containing an
entire FreeBSD distribution:
D=/here/is/the/jail
cd /usr/src
mkdir -p $D
make world DESTDIR=$D
cd etc
make distribution DESTDIR=$D
cd $D/dev
sh MAKEDEV jail
cd $D
ln -sf dev/null kernel
Clearly, this doesn't work on a 5.0 system if you want to
set up a 4.7 jail.
