Thank you Rainflurry for your time and answer.

As long as you have an accountable plan and your home office is used as your principal place of business and it is used exclusively for a home office then, yes, you can be reimbursed by the S-corp.

This is the point I am little bit confused. What I am reading from internet is, S-Corp can "mark" this as expense, but the "employee" can't ask for reimbursement for home office as per IRS regulations.

If the "you can" here means, business owner, then "accountable plan" is not something applicable for business owner, isn't it? or am I misinterpreting things?
