'^{{ ansible_hostname }}$' matches a line containing only the name of
the node currently running the task.

If you want to delete a line starting with the name of the node you'll
need '^{{ ansible_hostname }}', without the $ which means line end.

If you are getting an error, providing the error message would help ...

it is working now,

with below syntax.

lineinfile: dest=/tmp/node/test.new

                  regexp='^{{ansible_hostname}}'

                  state=absent

      delegate_to: "{{ groups['masters'][0] }}"

      changed_when: False
