Sure you can, you get more power with more directional antennas.
Here's a company that will sell you everything you need:
They can get 25 miles. Using a 36db Yagi you can build the same thing
yourself, as many have done. You do have to back off the transmitter
slightly to stay within FCC limits, but 20+ miles 802.11b is easily
done within FCC limits.
I cannot speak to 802.11a, as I know nothing about how it works,
or the frequences and power involved.
