No, not specifically.

According to http://en.wikipedia.org/wiki/Wake-on-LAN:
"The Magic Packet is a broadcast frame, transmitted over port 7 or 9. It can
be sent over a variety of connectionless protocols (UDP, IPX) but UDP is most
commonly used. The data that is contained in a Magic Packet is the defined
constant as represented in hexadecimal: FF FF FF FF FF FF followed by sixteen
repetitions of the target computer's MAC address, possibly followed by a four
or six byte password."
Port 7/udp being echo and port 9/udp being discard, I don't see why you
couldn't block these ports.
Gr,
Rob
