Does it state anywhere on the container the following?
"Use this product as a food supplement only. Do not use for weight reduction"
If it does, then no you probably shouldn't use it to 'replace' a meal.
You would use it to bump your protein needs.
Just my suggestion: If you continue to have it at lunch time as a supplement then add a small meal so you're having at least 300-350 total calories. Depending on the macros your protein drink has; choose something to balance out the higher protein with some healthy carbs and fats.
