Yes.
Not entirely sure about max HR, but field tested LTHR it's definitely true for most people.
I've seen it in my own field tests, and its the reason my coach made me test HR separately for running, when I was doing a HR based program.
There's some individual variability here, and may in part depend on your experience and training in each discipline.
