Depends on the complexity of the machine as it only has 13 digital input/output pins and 5 analog input pins but I cant see why not!

from the sounds of it it may be too much for a uno but a Arduino Mega should be fine.

use i2c lcd and put a resistor network on the keypad in order to use one analog pin for the keypad a and 2 outputs for the lcd leaving you 15 inputs/outputs
