No! ${lookup isn't an expansion condition.
To rewrite the original condition more readably...
condition = ${if and{{ !def:h_X-Spam-Flag: } \
{ !eq{$received_protocol}{spam-scanned} }} \
{yes} {no} }
You can then add the lookup in the true branch of the ${if...
condition = ${if and{{ !def:h_X-Spam-Flag: } \
{ !eq{$received_protocol}{spam-scanned} }} \
{${lookup {$local_part@$domain} \
lsearch {/etc/mail/filtered_users} \
{yes} {no} }} \
{no} }
