Nope.  That's even explicitly called out in Documentation/process/coding-style.rst:

  Do not worry about panic_on_warn users
  **************************************
  
  A few more words about panic_on_warn: Remember that ``panic_on_warn`` is an
  available kernel option, and that many users set this option. This is why
  there is a "Do not WARN lightly" writeup, above. However, the existence of
  panic_on_warn users is not a valid reason to avoid the judicious use
  WARN*(). That is because, whoever enables panic_on_warn has explicitly
  asked the kernel to crash if a WARN*() fires, and such users must be
  prepared to deal with the consequences of a system that is somewhat more
  likely to crash.
