Nope. The vowel changes significantly for both, but the presence/absence of "n" remains fixed.

"trundle" is related to "trend", also German "trent" and "entrinnen".

"tread" is related to "trot" and "trade".

It looks like "trade" changed meaning significantly between Middle English and now, even though they only converge all the way back in Proto-Indo-European.

ModE tread < MidE treden < OE tredan < PWG *tredan < PG *trudaną < PIE *dreh₂

ModE trade < MidE trade (meaning "track") < MLG trade < OSax trada < PG *tradō < PIE *dreh₂

Also possibly related, assuming we merge the PID *dre_ variants which all have similar meanings:

  tramp[le]
  trap (something that gets stepped on)
  dromedary
  palindrome (run back again)
  ? troll
  ? dorm (allegedly there's an old "sleep" meaning with the same spelling - this is unrelated to "dream, draugr" which means "deceive" though!)
