Yes, if you don't receive anything that is fine. However, just using the delayed ack timer would not fulfill the requirement of one ACK per RTT. Assume a scenario where you send packets and you ack the last packet and then send nothing for about one RTT and then send one more packet. In that scenario you should ack immediately because you didn't send an ACK in the last RTT and should not wait for the delayed ack timer to expire.
