You can, even though most do require work experience (usually 2 years full time) you can do an MBA straight away if you have high enough grades, from what I remember reading is you need a GPA of 6 (I think, better you search it up, I checked this about 2 years ago in yr 10) or higher if you want to apply, obviously higher the better.
This is what I'm planning on doing, my Bachelors, then either Masters in Economics or MBA (I'm doing both masters just don't know which first, probably Eco first tho)
