If you were to change the width substantially they might not work on your wheel - wheels typically have a recommended minimum and maximum tyre width (it might be listed on the wheel itself). It's hard to see how changing from 700x40 to 700x35 or 700x38 is going to cause any problems.

I'm assuming you have a hybrid bike. All 2 sizes you mention will fit the same rim with no problem. If original tires were 42's, it may be near the max allowed tire width. On the other hand, you can go down to probably 700x32 or even less without any issues.
If you know the rim name, you can look it up online.

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
at 42mm or so, it might be a typo with the decimal in 1.65 missing.

Yes, you would be OK with any 700c tires (622 is the actual rim diameter in mm, btw).
The smaller tires will lower the bike a little (40mm = 2mm lower than stock). This becomes a big deal if you lower it so much the pedal scrapes. On your hybrid, you can probably lower it a cm before you get into trouble. Thus, 32mm may be a sane minimum. It depends on how high the cranks are (aka bottom bracket height). Most hybrids have medium to high bottom brackets.
The larger tires will raise the bike a little, by the same reasoning. The limit for large tires is the clearance of the frame. If you put a 2 inch / 50mm mountain bike tire on your rims, it may rub against the frame on the sides, on the top, or hit the brakes. Look at your current tires and measure how much clearance you have wherever the bike frame/brakes come closest. That should give you a rough idea how much bigger you can fit.
In this range, a few mm won't make too much difference in the ride.

I wouldn't go from 700x42 to 700x25 without checking the rim will be OK. You don't want tyres working loose because they are too narrow for the rim. If you're not making big changes you should be OK.
