On the command line, no.  But if you're building from source you could
tweak it and make a version that does.

For instance in the 1.2.30 code:

$ find . -type f -exec grep "24\*365" /dev/null {} \;
./bindings/tcl/tclrrd.c:            if (last_up < 3600*24*365*10) {
./src/rrd_create.c:         if (last_up < 3600*24*365*10){
./src/rrd_fetch.c:    if (start_tmp < 3600*24*365*10){
./src/rrd_graph.c:    if (start_tmp < 3600*24*365*10){
./src/rrd_graph_helper.c:    if (start_tmp < 3600*24*365*10) {

Each of those lines appears to be constraints to 1980 and later.  Tweak
the "10" down a year or two and recompile should work.
