Yes, this is true..

A channel modeled with one tap is a flat fading channel because there
is only one tap i.e. a single multiplication operation. Upon adding
multiple taps, you are then conducting a convolution operation that
can model a frequency selective channel. Check Sklar book and his
famous journal paper on fading channels.
