We removed an old trelis but did not remove cement from under the grass. As a result, I have an area that is slightly raised higher than the rest of the lawn. Though generally the whole of the grass in the garden is uneven, how do I go about removing the concrete from under the grass (approx 2 mts x 2 mts) from where the trelis once was?

I am afraid that the only way I know if is to dig it out. You could try placing another feature on top of it or mounding more soil around it, but if you want the ground to lay flat, it will need to be removed.
