(current-buffer) returns an buffer and not the buffer-name.
You can check that with M-: (current-buffer)
Use (buffer-name (current-buffer)) and string-match. Or see below.

`if' also need an else part. Check C-h f if

The rewritten code would be better written like this:
(global-set-key (kbd "<f10>")
'(lambda ()
(interactive)
(next-buffer)
(while (member (buffer-name (current-buffer))
'("*scratch*" "*Messages*" "*Whitespace Errors*"))
(next-buffer))))
