Можно ли использовать Master's Thesis Preliminary Defense Date?

preliminary - может быть
defence - так, думаю, не говорят. Это, скорее, оборона.

Хотя, defenSe - американский вариант, и там, похоже, так говорят: https://www.google.co.uk/search?client=firefox-b&q=thesis+defenСe

В Англии часто используется Latin "viva":
In Hong Kong, Ireland and the United Kingdom, the thesis defense is called a viva voce (Latin for "by live voice") examination (viva for short).

Note: "In North America, the thesis defense or oral defense is the final examination for doctoral candidates, and SOMETIMES for master's candidates."

Так что, если не presentation , то viva или examination
