Yes, for jets, you must be very careful on takeoff and climb-out not to exceed IAS (below FL180) or Mach limits above. You can actually crash by exceeding either at any altitude.
Jets will over-speed quickly when you reduce fuel and passengers. No need to use 100% throttle on takeoff. Keep speeds to under 250 until you activate your FS/AT/AP.
