Yes, you can use a variable for a table name like that. But you need to make sure that variable is a) previously defined and b) a valid SQL tablename e.g. isn't a SQL reserved word and doesn't contain invalid characters unless it's delimited with quotes or brackets or whatever your RDBMS uses.

For example this won't work: 

my $table = "Robert dropped a table on his foot";
my sql = qq{SELECT * FROM $table WHERE x=?};

Whereas this might, depending on how your db delimits: 
my $table = "Robert dropped a table on his foot";
my sql = qq{SELECT * FROM "$table" WHERE x=?};
