Yes , but cutting Bulair,you have to have enough population, for defend too much land, by land and by sea, Constantinople was like an island, but a small one in comparison with the Gallipoli peninsula.

Pay attention to this map.
You see a city with litle connection with land. You don't have to surround the city with walls. You can block Golden horn. Byzantines blocked It with gian chains. During siege they can get help from the sea.
If she was located in Çanakkale or Iznik, I suppose East Rome wouldn't survive to that long.
Additionally, the scienery is far more beautifull in Istanbul.
ιn fact to the left of the map to the land side, after the walls excisted a dike, full of water, which were quite broad and deep, it took place from the Marmara Sea until the Cercoporta, so Constantinople to be called even by the last Byzantine in 15th century that is almost island
Constantinople was the perfect spot defense while being important starting point and the distance from the Asian coast less, which is important in transporting goods and troops.
The existence of hills used except geografical source diversity and beauty, as an Observatory for any fires and military and police purposes and for communication. The same also for Galata.
There was also a system of visual notification for troop movements. *
During a siege could either procure fish from the Golden Horn, either farm products stored in the warehouse after the city had large sizes, either cultivating even in the city during the Byzantine period, while the supply of goods by sea through the divisions when conditions allow an additional option.
This does not mean that the area of Troy and Çanakkale/Dardanelles is not significant and does not offer strategic advantages.
It seems that for strategic military reasons , and specially for defense Constantinople/Instambul was a better choice, and a safer place.
* The Byzantines had installed a series of beacons on mountain tops which ran from southern Asia Minor and came to beacon/lighthouse of royal palace of Constantinople.The message did less than one hour to reach from Lulo [ fortress in Taurus mountain] to Constantinople. This optical system was called "Oronomio" and it was the Byzantines Optical early warning system of the Byzantines to the Arabs.
Τhe system perfected by [ame="http://en.wikipedia.org/wiki/Leo_the_Mathematician"]Leo the Mathematician [/ame] (790 – after 869).
Leo has been credited with a system of beacons (an optical telegraph) stretching across Asia Minor from Tarsus to Constantinople, which gave advanced warning of Arab raids, as well as diplomatic communication. Leo also invented several automata, such as trees with moving birds, roaring lions, and a levitating imperial throne.The throne was in operation a century later, when Liutprand of Cremona witnessed it during his visit to Constantinople
