Yes.  You can use the embedded script to send a custom HTTP GET request, such 
as

  #!ipxe
  chain http://192.168.0.1/boot.php?mac=${mac}&serial=${serial:uristring}

You can implement boot.php to do whatever you want in response to the 
parameters passed via the HTTP GET.  For example, if your boot.php decides to 
create a new iSCSI target and direct the client to boot from it, it could 
return another script:

  #!ipxe
  sanboot iscsi:192.168.0.123::::iqn.2010-12.com.example:52:54:00:12:34:56
