That gives:
E119: Not enough arguments for function: submatch
E116: Invalid arguments for function MyFunction(submatch())

The following works on my system:

function! MyFunction(m)
let x = len(a:m)
return x
endfunction
%s/'pattern'/\=MyFunction(submatch(0))/gc

Testing on following gave a confirm for each change.

'pattern' hello 'pattern' hello 'pattern' hello
