^^^^ Impossible to say for sure, but unlikely. Put a small piece of tape on the stem to indicate its current position, then pull it out all the way. Look for a mark referring to its maximum height. It'll either be a line with an arrow pointing to it, or a set of "hash marks" going around the stem. It'll also say either "Min insert" or "max" or "max rise" or the like. That will tell you how high you can raise it, and still be safe.
