Yes, it's possible.

# match icmp echo request
tc filter add dev $dev protocol ip parent x: u32 \
 	match ip icmp_type 0x08 0xff flowid 1:2

# match icmp echo reply
tc filter add dev $dev protocol ip parent x: u32 \
 	match ip icmp_type 0x00 0xff flowid 1:2

See /usr/include/linux/icmp.h for more types.
