Technically yes, but is there is a reason for users to adjust this particular behaviour? Users dissatisfied with the outcome of the existing algorithms typically curse and set colours explicitly (or suffer in silence); they are unlikely to set a 'use different algorithm' variable.
To be precise, the computations I suppose we are talking about are located in:
frame-set-background-mode (frame.el:1184)
xterm-maybe-set-dark-background-mode (xterm.el:1122)
rxvt-set-background-mode (rxvt.el:198)
terminal-init-w32console (w32console.el:89)
which all use the predicate (r+g+b)/3 < 0.6 to determine if a colour is dark.
It is also mentioned in a comment in pc-win.el:57.
I believe it to be suboptimal but have no plans to do anything about it.
