It is compulsory to link Aadhaar and PAN before Mar 31, 2019 otherwise your PAN will become invalid.
I don't think it will take that long for change in Aadhaar details. Give it a shot for future, they may revise dates once again.
You can link it later also. There is no clarity on what invalid PAN means.
