He was appointed an Officer of the Order of the British Empire in June 1923, the citation reads, "This officer has done exceptionally good work in connection with Signals. His liaison with the Navy and the Army has been excellent."

Linnell was posthumously invested as a Commander of the United States Legion of Merit in recognition of his outstanding services in the Mediterranean theatre of operations from 29 February – 29 June 1944. The decoration was presented to his widow, Lady Linnell, by Brigadier General E. F. Koenig at a special ceremony in London.

Project Upkeep
Linnell was apparently against the idea of a bouncing bomb reasoning that it was drawing development resources away from the prototype high altitude bomber Vickers Windsor, his thinking may have been influenced by Charles Craven, the Chairman at Vickers.

Early in 1943, tests authorised by Linnell in June 1942 at the instigation of Sir Henry Tizard, indicated that a bouncing bomb was technically feasible. A meeting between the Air Ministry, RAF Bomber Command and MAP decided to continue development of project Upkeep with a proposal to have a fully trained squadron ready by May. AOC-in-C of RAF Bomber Command Harris thought differently and saw the project as a waste of precious Lancasters. However Chief of the Air Staff Portal was convinced by film footage of the tests and ordered three Lancasters allocated to the project. One week later, at a meeting convened by Linnell, the number of Lancasters ordered had risen to a squadron and Operation Chastise was planned for that spring.

Personal life
Only son of William Henry and Kate Linnell, he had one sister, Marjorie Clare. On 26 May 1917, 'Jack' married Margaret Christabel Carpenter of St Leonards-on-Sea, Sussex, at Christ Church, Turnham Green. They had no children.
