Computers & IT (Non-Engg)

Yes, you can. Artificial Intelligence (AI) is a cross-disciplinary topic. It involves three main things. First, you need to know programming (in any language but Python is better). Second, you should be good at math and logic (algorithms) and third you need have domain knowledge of the problem you are solving. First and second skills are common for all the problems so you should learn them in the beginning. Learning Programming and math takes time and you become good ATIT by doing more of it. I would suggest you learn Python as it is a de-facto language for machine learning and deep learning. You can go through this video tutorial series: Python Programming Tutorials.
For learning maths (algorithms), you should read good books. Please refer my answer:
