can we override the Mark Complete and Save button with a lightning action button in the Task detail page? I checked the Buttons, Links, and Actions section in the Object Manager but these are not available.enter image description here

Also, can we add an error message against the Mark Complete buttons(Like OnClick action)?

No Sam you cannot override the Mark complete and Save button directly.

The possibe workaround would be, creating the new lightning components (with implementation of lightning:actionOverride interface) for each NewTask and StatusChange buttons.
