Yes, I don't believe there was ever a white Beylauncher released (other than the L that came with L-Drago 105F, Lightning L-Drago 100HF, and Meteo L-Drago LW105LF) but you can always buy a stadard Beylauncher and paint it white, or customize it with any color, decal, ect., as long as it does not improve nor hinder the performance of the Beylauncher itself.
There was a silver (?) one released with the BB-107 Big Bang Pegasis DX Set, so that's probably the closest thing you'll find to white one.

He is referring to a white one, not all Beylaunchers in general.
