My Lc would probably not get off-road time that would require 4low or centerdiff locked. Even if this is the case,.do we need to engage these features every so.often just to prevent things from breaking down or just get things lubricated
Do we need to engage 4low and diff lock every so often to prevent damage to the system?

Do you have AWD, full time or part time 4WD?
AWD means all the parts are moving all the time.So no worry about parts seizing up.
In full time 4WD all the parts are moving all the time but not necessarily connected. So no worry about parts seizing up.
In part time 4WD the front axles (with locking hubs) and the front diff are not moving if you are in 2WD. So every so often lock you hubs and go to 4H for a short distance. Even though the front output shaft in the TC is not turning in 2WD it is open to the rear wheel drive gears and should be adequately lubed. If your TC has manual linkage that needs occasional movement as well to keep it from seizing.
The 4L side of the TC should get adequate lube from the 2H parts of the TC.

Is that wrong?
I didn't see that he has a 200 in his sig line and missed that it was the 200 section.
Although, there are many 200s built with a part time 4WD, just not sold in the US, and he does say he is from Asia.
I think it is a good idea to exercise the low range. Once a month I take my Cruiser out in the country and put it in low range, drive it that way for a few miles. I have an 80, so I shift the locking differentials in and out to keep the mechanisms working. I notice as I have done this, all the systems to work better.
Do it one time at least right before the drivetrain warranty expires 
Yes, you should lock the center diff and shift into low range occasionally. Make sure you are on dirt when you do this and drive around some.
