For me your file worked all right, centered to page, in Windows and Linux. The only reason I can imagine is you have been in Print Preview, the drawing was not centered there, you leave Print Preview and then do export to pdf.
 Stay in Print Preview, after having positioned the drawing there, while exporting, to ensure the expected result.
