Yes.  BIND 4.8 and earlier allowed you to put multiple zones in the same
file.  I remember a number of web hosting companies being disappointed when
they upgraded to 4.9 and couldn't do this any more, because they didn't
like having to have thousands of little files just to hold an A record for
each www.<customer>.com.
