No. the pressure are different, r22 runs at a fairly low pressure and you shouldn't be worried about blowing your gauges, but you won't be able to determine your super-heat or sub-cooling. for a about $100cdn you can buy the right gauges.

Difference between bar and barg?
The 'g' added on to bar means 'gauge', as opposed to bara, meaning 'absolute'. The 'zero' of a normal gauge is normally set at atmospheric pressure (things like tire pressure gauges, water gauges etc.) These gauges will read as "10 bar" but really mean that the absolute pressure is 10 bar + atmospheric pressure (~1.01325 bar). Some gauges however are absolute gauges. These might include weather gauges, or gauges on closed processes. bara = barg + atmospheric pressure
What is check gauges for 1999 Chevy Tahoe?
When one of your gauges shows something abnormal, your "check gauges" light will come one. Chances are you're low on motor oil. When you corner, the oil will slosh away from the pickup, causing your oil pressure gauge to read zero for a second. This in turn causes your check gauges light to come on, but by the time you look at your gauges, the oil has settled in the pan is your oil pressure is reading normal again. When you see the check gauges light and the gauges are reading fine, check your oil.
