I am working on minimizing power consumption using deep sleep mode. Every time the ESP wakes up from sleep it writes info through the serial port, making the TXD LED light up. Can I remove this LED?

Yes, try removing the LED (do not solder the left over pads together) and test your software. Removing the LED would also remove the pull up on the TX line, but in most cases this shouldn't cause issues.
