In general, yes you can. I did it on my (UK, so PAL) Tandy CoCo 2 for many
years. Sometimes you need a 1 or 2 transistor video amplifier, and it
often helps to turn off the termination switch (labelled '75 Ohm'?) at the
monitor - the video stage that drives the modulator will often not drive a
75 Ohm load (and if you keep the cables short reflections are not a real
problem).

Give it a go. You're unlikely to damage anything.
