You can have fakedomain.com point to the same IP address as one of the 
name servers, yes.

The second name server will need to point to a different IP address.

So, you might have

fakedomain.com.             1D IN A          aaa.bbb.ccc.ddd
ns1.fakedomain.com.         1D IN A          aaa.bbb.ccc.ddd
ns2.fakedomain.com.         1D IN A          eee.fff.ggg.hhh
www.fakedomain.com.         1D IN CNAME      fakedomain.com.

fakedomain.com.             1D IN NS         ns1.fakedomain.com.
fakedomain.com.             1D IN NS         ns2.fakedomain.com.
