In a word "Yes". The bigger question is: can you remember to take it twice a day...at the proper time? If so, then you can ask your doctor for the chance to try it.
When I made that same switch a few years ago, I went from 100mg Toprol XL once a day to 100mg metoprolol succinate once a day. Neither my doctor nor my pharmacist ever suggested that I would need to split the dose. My understanding is that metoprolol succinate is an extended release formuation that substitutes directly for Toprol XL. But ask your doc or a pharmacist to make sure. I'm off of the drug entirely now, so I don't worry with it anymore.
