Probably you want the search() function, which will return 0 if no matches are found in the buffer.

More explicitly, try something like this (untested):

:source foo.vim

where foo.vim contains the lines

if search(';', 'cnw')

  echoerr 'Corrupted file. Please check for semicolon character.'

  finish

endif

%s/\<emacs\>/vim/g

:help search()

:help :echoerr
