You can’t use \define but it creates non expandable commands
(which can be solved when you use \defineexpandable instead)
and there is no need for this extra step.
\starttexdefinition doTableRowExpB #SET
\bTR
\expanded{\bTC\getvariable{#SET}{a}\eTC}
\expanded{\bTC\getvariable{#SET}{b}\eTC}
\expanded{\bTC\getvariable{#SET}{c}\eTC}
\eTR
\stoptexdefinition

Great. This does the job, and allows assigning more
semantically-meaningful names to the elements.
\starttexdefinition doTableRowExpB #SET
\defineexpandable\A{\getvariable{#SET}{a}}
\defineexpandable\B{\getvariable{#SET}{b}}
\defineexpandable\C{\getvariable{#SET}{c}}
\bTR
\expanded{\bTC\A\eTC}
\expanded{\bTC\B\eTC}
\expanded{\bTC\C\eTC}
\eTR
\stoptexdefinition
I see no performance difference on a much larger test, and I think that
the readability is improved (and thus the opportunity for simple
mistakes) when the hundreds of \getvariable macros are refactored into a
few macro definitions.
maybe the next can convince you then
\starttexdefinition doTableRowExpB #SET
\expanded {\bTR
\bTC\getvariable{#SET}{a}\eTC
\bTC\getvariable{#SET}{b}\eTC
\bTC\getvariable{#SET}{c}\eTC
\eTR}
\stoptexdefinition
with
\starttexdefinition doTableRowExpB #SET
\normalexpanded {\bTR
\bTC\getvariable{#SET}{a}\eTC
\bTC\getvariable{#SET}{b}\eTC
\bTC\getvariable{#SET}{c}\eTC
\eTR}
\stoptexdefinition
being a bit faster
