Yes you can whit a atmel programmer or using the bit banging mode of the ftdi chip on your arduino (  If you have duemilanove) Use this guide and remove the old atmega on the arduino and put the new atmega , now you can see the guide http://www.geocities.jp/arduino_diecimila/bootloader/index_en.html
