Did John Lennon had dyslexia

No, Bono doesn't have Dyslexia So far as we know, none of the members of U2 have any learning disabilities, though Bono and The Edge did appear at a charity in November, 2007 to raise money for Mencap (a UK organization that helps people with learning disabilities). "Don't tell Larry and Adam we did this," Bono quipped. Billed as the warm-up act for one of Mencap's Little Noise Sessions, the identity of the 'special guests' was kept secret. Host Jo Whiley introduced the duo as "a new band with a lot of potential…Dave the guitarist is very nervous…If he makes a mistake forgive him, he's new. The singer is very shy."
